To all whom it may concern."

Be it known that l, NELSON F. BRIGHAM, a citizen of the United States ofAmerica, residing in Holyoke, county of Hampden, and Commonwealth ofMassachusetts, have invented certain new and useful improve hardened,they are then flooded with or dip-.

ped in chocolate; which forms the coating. They are then allowed to cooland are then ready for packing.

Broadly stated, the presentiinvention re- '7 lates to the'method of andapparatus for partially forming the coating of a confection, thenfilling the partially formed coating with the filling material andfinally closing the coating or completing the confection. The means thatI have devised for carrying out this process comprises a rotatablemember or mold having a suitably shaped de pression therein whereby whenthe coating is in a semidiquid or melted state and at a suitabletemperature is introduced into the depression of the mold and rotated ata suit able speed, the coating material will be forced up the innerwalls of the depression, by the combined action of gravity andcentrifugal force. The member is thenbrought down to a suitable speed ofrotation or the rotation stopped if desired, it being assumed that thecoating material has then set or cooled sufiiciently to receive thefilling mate rial. The filling material is now introduced, after whichthe remaining portion of the coating is added, and, after uniting withthe previously formed partial coating thus formin the completeconfection.

efere'nce is made to the drawings form ing a part of the application tothe detailed description and claims which will specifically point outthe improvement.

Fig. 1 illustrates, in section, a machine having means for rotating themold into which the coating material is introduced.

Fig. 2 shows the coating material being introduced into the mold andalso illustrates a modification in which the coating material ifdesired, may be forced into the bottom part of the member or mold.

Fig. 3 shows the coating material having 7 been forced up the inside ofthe mold and set suficiently for the introduction of the fillingmaterial.

Fig. 4 shows the partially formed coating filled with the fillingmaterial.

Fig. 5 shows the remaining portion of the confection closed with theaddition of a suitable coating material;

Fig. 6 is a modification in which the inside of the mold is providedwith a paper lining or other suitable material into which the coatingmaterial is introduced, whereby when the confection is completed, it iswrapped and covered.

Fig. 7 indicates the idea of forming the mold with a design. 7

Fig. 8 is a modification in which the mold 'is formed in sections withmeans for holding to throw the surplus coating material up the sides.

Fig. 12 shows the coating material-after being melted-to complete theconfection.

. Referring to the drawings in detail: 1. indicates a rotatable member,which is secured or attached to the shaft 2, that carries,at its lowerend, the pinion 3 which meshes with the gear 4, operated from the shaft5 through the gears 6 and shaft 7. Mounted in the member 1 is a moldmember 8 and mounted on the upper end of the mold-member 8 is a plate 9that is attached to the bowl '1 by means of the thumb screw 10 and latch11. The lower part. of the bowl 1 is also formed p with a curve andmerges into the curved surface of the members 8 and 9 as indicated at12. a

Referring to Fig. 2, 12 indicates the semiliquid or melted coatingmaterial introduced into the'inold from the receptacle 13 beforeorduring the rotation of the mold. lhis coating material is introduced atthe proper temperature. As the member is rotated at a constant orvariable rate of rotation, the coating material will be forced up theinner surface of the mold to form a thin layer of the coating materialindicated in Fig. 3 at 14:. This act of being forced up the innersurface is a- .well known principle in physics andmechanics, and asshown in Fig. 3 the coating material may be' considered as having setforming a partial coating for the finished confection. The upper part ofthe coating being indicated at 14, leaving an opening 14 at this part ofthe confection with the thin edge as shown at 14 Referring to Fig. 4,which illustrates the filling material of the confection at 15, afterthe same has beenv introduced into the partially formed coating shown'in Fig. 3, it being understood that the mold is now being heldstationary, or driven at'a low rate of rotation, the next step in themanufacture of the confectionis completing the remaining rtion of thecoating of the confection as.

indicated at 16 in Fig. 5. This is accomished by adding a suitablecoating material a) the filling 15, the edges of the part 16 adhering toor uniting with the edges 14c of the already formedcoating 14 as indi iated at 17 of the opening 14 0f the coating.

If desired, the bottom of the mold 8 may be formed with a suitableengraved symbol as shown in Fig. 7 with the letter V, to indicated thatthe confection is of vanilla flavor. When the coating sets the V isdistinctly shown. Other designs may be shown.

Referring to Fig.6, 18 designates a lining of paper or other suitablematerial that is first inserted in the molds 8 and 9, or other holdingmeans, the material if paper being first preferably twisted together asindicated at 19, the twisted portion being received in the opening 20 ofthe bowl 1. After the confection is formed in the manner alreadydescribed, the upper part 21 of the casing is folded inward, thuscompletely enclosing the confection, whereby when the molds S and 9 areseparated, the confection will be wrapped thus producing a sanitaryarticle.

material, m object being to provide a in:

through which the coating mate-- rial 1s pt olds may be made of anysuitable sections are cut out to form the depression 31 into which thecoating material is placed. The lower end of the sections are formedwith depending projections 32 through which are passed pivotal pins33-for attaching the sections to the plate 34:. This plate is formedwith an integralqcollar -35 throughwhich passes the driving shaft 36that is formed with a tapered upper surface 37 which surfac'e fits acorrespondingly shaped opening 38 at the lower part of the sections'30.The shaft 36 is keyed tothe plate 34 as indicated at 39. This key isformed with a sliding fit to permit the shaft 36 to be raised, or themold lowered, whereby when the cap 40, which holds the sectionstogether, is removed the sec-lions can be forced apart by the taperedsurface of the shaft 36 and the confection readily removed. The coiledspring 41' serves to draw the sections together again,

coatingmaterial up to the line 42, it is then rotated and the surpluscoating material may be thrown off from the topedge 43 of the funnel 9by centrifugal force, leaving a coat- .ing which covers the inside ofthe mold8 closed to allow an electric current to flow throughthe'heating' coil 16 for melting the coating material Mon the inside ofthe funnel 9, which will flow or run downward onto the filling it andform the closingor base part 16 of the coating of the confections. Themold is now opened by means of the construction shown and described inconnection with figuresB, 9, and 10.

ft is to be understood that mold 8 of my improvement is not limited toany particular shape as the recess instead of being in the form shownmay he of any suitable shape. hen the mold is rotated the inner surfacethe coating or lining of the confection will, of course, assume theshape of a parabola, irrespective of the shape of the recess into whichthe coating material is introing of the confection, next stopping therotation of the mold and introducing the fill-- ing material, nextcompleting the coating of the confection by adding material on to thefilling material and allowing it to unite with the coating firstformed'whereby the coating" is completed and the filling is completelyencased.

2. The method of forming a confection which consists in introducing thematerial which isto form the coating into a mold, then rotating the moldwhich operation results in forming a lining on the interior of the samewith the-material when in a plastic or melted condition and allowing thesame to set during the rotation of the mold, thus forming a partialcoating for the confection, then introducing the filling material andfinall completing the coating by adding an additional quantity of acoating material.

3. The method of forming a confection which consists in introducing acoating material into a revolving receptacle said substance, by thecombined action of centrifugal force and gravity Will conform to thecontour, of the receptacle to form a partial coating for the confectionwhen the same has set, next introducing the material which forms thefilling of the confection into the partially formed coating and finallyclosing the partial coating.

4.
